On a benchmark of 250251 compounds in the NCI00 database, mol2nam
is able to convert 220922 structures (88.28%) to names without BLAH.
Of these 220922 names, nam2mol is able to convert 177032 (80.13%)
back into structures.

In addition to a great many other improvements to the name parsing code,
the Lexichem parser now contains an internal dictionary allowing the
recognition of common non-systematic names, such as ‘ranitidine’
and ‘zantac’.

In addition to a great many improvements to the name generation code,
the Lexichem naming functionality now allows the specification of a
naming style, allowing the compound to be named in either a
traditional, OpenEye, IUPAC, CAS or systematic naming style.
